LOCOMOTIVE.

Specification of Letters Patent.

Patented J an. 4, 1916.

Application filed August 20, 1914. Serial No. 857,719.

To all whom z't-may concern:

Be it known that I, WILLIAM F. KIESEL,

My invention relates to electric locomo-- tives and more particularlytothe construction and arrangement of the pony trucks thereof.

. The invention has for one of its objects to provide means whereby theload on the truck is carried at three points, thus giving a three pointsuspension, together with means for attaching a brake mechanism theretofor the purpose of increasing the braking safety factor of thelocomotive to which it is applied.

Another of the objects is to provide a practical method of weightequalization whereby the weight of the locomotive carried by the ponytruck is transferred not only to the journal boxes of the said truck butalso to the journal boxes of the main drivers of the locomotive throughan equalizing beam and spring arrangement.

The above and other objects, and the novel features of my invention willbe apparent from the following description,

taken in connection with the drawings, in

. which Figure .1 is a central longitudinal sectional view of theforward end of the locomotive truck, the cab thereof being shown inoutline; Fig. 2 is a top plan view of a pony truck constructed accordingto this f-invention; Fig. 3 isa transverse cross-section on the line 33of Fig. 2; and Fig. 4 is a side elevation of the pony truck.

Referring to Fig. 1,- 10 and 11 designate the forward main driver shaftsor a-xles which have pairs of wheels 12 and 13 fixed thereto at the endof the axle.

The axles also support suitable journal boxes 14 upon' springs 21 bymeans of links 22 which are pivoted to the side frame member 20. Thesprmgs 21 each consist of a plurality of superposed fiat spring platestied together by a band 23 and fulcrumed at the upper end of the bracket15 which rests on the journal box 14.

Equally distant from the driver axles 10 and 11 are two pony truck axles24 and 25 whlch have pairs of pony truck wheels 26 and 27 fixed theretoon the ends thereof.

The pony truck frame 28 is shown in Fig. 2, and consists of a singlecasting substantially in the shape of the letter A, the cross bars 29thereof representing the tran som bars between which a pair oftransverse springs 30, 30 is hung. The springs 30, 30 each comprise aseries of superposed fiat spring plates tied together by bands 31, thetops of the bands extending above the upper edge 32 of the adjacent partof the truck frame. vThe bands 31 carry the truck bolster casting 33upon which rest the angle plates 34 which are riveted to the- .inside ofthe side frame members 20 of the truck. It will therefore be observedthat the weight carried by the truck is transferred from the locomotiveframes to the truck springs 30 through the truck bolsters 33.

At the ends of the cross bars 29, 29 of the pony truck frame and nearthe outside edge of the frame there are cavities 35 open at the bottomand top and separated from the spring opening 36' by cross members 37.The pair of springs extending into the spring compartment 36 issupported at its lower side by cross-bolts 38 which are hung from thelinks 39, 40 and 41. The link 40 is thicker than the outside links 39and 41 and is disposed between the ends of the two springs. The linksare each T-shaped, having a head 42 disposed in the cavity 35. The loweropening 43 in the cavity is of smaller size than the head 42 of eachlink whereby the links will be retained in place, should the primarysupporting means fail, by the shoulder 44 thereof engaging the ledge 45at the bottom of the cavity. The primary supporting means for each groupof three links at the ends of the springs comprises a pair of crossbolts 46 and 47 which extend through openings in the head 42 of each ofthe links and have their ends resting on ledges in the cavity. Brackets48 and 49 are .hung from the cross members 29 and pass under the springs30, being spaced therefrom and serving to hold up the springs in casethe bolts 38 or any of the spring hanger links or parts fail.

Brackets and 51 are formed integral with the frame and are locatedoutside the cavities 35 on the transverse central line of the truckframe. The brackets 50 and 51 extend upwardly above the surface 62 andhave spaced parts 52 and 53 to receive between them the upper end of abrake lever 54 which has 1pivoted thereto the brake head 55 carrying t-mernbers 52 and 53 have co-axially arranged holes 57 drilled therein torecelve the pin 58. whereby the brake levers 54 may be pivotally securedto the brackets. slots or spaces 59 in the brackets are so positionedthat the brake hangers and brake heads. will be located directly in linewith the Wheels 27 of the truck.

The legs 60 and 61 of the truck frame are parallel and have journalboxes 62 and 63 at their ends to fit the axle 25 whereby the frame isrockably supported at two points on the said axle between the wheels 27.I

As will be seen from an inspection of Figs. 3 and 4,, the frame 28 hasconverging parts at one end and is of open-work construction and hasfront and rear inclined bracing members 64 and 65 joined togetherbyhorizontal bracing members 66 which are connected to the mainhorizontal portion 67 of theframe by vertical bracing parts 68. The top69 of the frame has a spherical socket 70 in its lower side in whichfits the hemispherical ball member 71 located near the lower end of avertical hanger rod 72. The hanger rod 72 extends through guide sleeves73 located on opposite sides of the top end 69 and held in position bybracket members 74 connected to the main side members 20. The pony truckframe has an opening 75 therein through which the rod 72 extendsupwardly where it is pivotally connected by va link 76 near the centerof a cross beam or bar 77 which is supported at its ends on the oppositeends of the springs from the links 22.

The main driving springs 21 positioned above the journal boxes of themain drive axles 10 and 11 constitute a spring equalization and transferthe weight of the locomotive and frame 'to the main drive axle. weightof the locomotive and frame, supported by the transverse springs on thepony truck 1s partly transferred to the pony truck axles at two pointsand partly transferred to the main driver springs at one point and fromthem to the main driving axles, thereby efiecting a three pointsuspension of the weight carried by the pony truck frame.

While I have shown and described my invention in detail, I do not wishto be limited to the exact construction shown and described as t isevident that numerous e brake shoe 56. The spaced The The-
